Until recently, scientists thought only tsunamis were capable of moving gigantic rocks weighing tens and hundreds of tonnes, but geologists have recently found that storm waves are just as powerful. Amaze your students with this geology resource that explains the difference between tsunamis and storm waves, their effects on coastlines, and why climate change and the increase in storms could affect people living near the coast. Included is a summary of a current research project, an interview with geologist Dr Ronadh Cox and a career guide for students interested in geology. The activity sheet includes discussion points – seven questions the students can answer in groups of individually –, and instructions on how to weigh objects that are too heavy to move.
